USB problem

The usb port on my ThinkPad hasn't been functioning recently. I have posted
some screenshots at www.geocities.com/areluc/thinkpad/. As you can see
there, I have a mulfunctioning USB Root Hub. When I go into properties, it
tells me I should update the driver. I have downloaded a usb driver for my
specific laptop model from the IBM site. However, when I try to use it by
pointing to its location, the system tells me that the best driver is
already installed and there's no way I can change it. Same with MS Windows
Update. When I remove the hub and even the host controller, they
automatically reinstall themselves exactly as they were. As a result,
nothing I connect to usb port works! Does anyone have any idea how I can fix
this?

Thanks,
Lucar

Boot to Safe Mode. Go to Device Manager. I suspect that you will see
several "phantom" devices in several areas but especially in the USB
section. Remove *all* devices in the USB section. Reboot. The USB
section might be rebuilt automaticall, but if not then install drivers
manually starting with the driver for the host controller. Reboot
between installs. Then go back to Safe Mode and remove *all* entries
for devices with multiple phantom entries so those are cleaned up.

If this fails to work, then save your files and do a clean reinstall of
Win98.

Is the info shown in the link correct, it uses 82371
southbridge? If you don't know, I'd assume it does... that
is natively supported in Win98 or newer (WinME, 2K, XP,
etc), you do not need a driver other than the support native
to windows.


However, when I try to use it by
pointing to its location, the system tells me that the best driver is

Had the system's USB *ever* worked properly? I'll presume
so but did it in your presence, when you received it? What
has changed since that point? Driver or system config
changes? Hardware added? OS updates? What OS?

Frankly I would NEVER use windows update for drivers. There
is no good reason to, it can only be same or worse than
respective driver from the hardware manufacturer (which in
this case might be considered IBM but is actually Intel as
it's their southbridge providing the function... but again,
this would be if you had Win95 in this specific case, since
all newer versions of Windows have built-in support.

Well, I mean drivers specific to the hardware, not
necessarily patches to the OS files.

When I remove the hub and even the host controller, they

Thanks for your tips. Yes, it worked ok until I installed mobilePhone Tools
from Motorola to upload the pics from my phone. During installation it
recognised my phone model and asked for a driver, however at that time I
didn't have it. Later I downloaded the driver but the usb port was not
functioning already.

Do you think installing Win98 over the existing version would also work?
Without usb I can't back up the data - it's a fairly old laptop with only
cd-rom drive.

How about a Compact flash card & adapter for backup?

you can try installing win98 over itself, it has been know
to fix some problems but I couldn't guess if it will help in
this case.
